The results of a comparative analysis of the vitality structure of Acer negundo populations during ontogenetic development in an urban environment are presented. The vitality structure of A. negundo populations is changing from prosperous to depressive, with the changing living condition of individuals and the quality of populations in urban conditions. The quality index of A negundo populations was in the amplitude from 0.5 to 0.166 along the urbanization gradient. High plasticity and variability of A negundo in combination with the dynamic vitality structure on the background of anthropogenic impacts provide active colonization of this invasive species in the city.
